Kiwi golf ace Lydia Ko's new coach is being credited with playing a vital role in the turnaround in form that's brought an end to her title drought.
Amid the raft of changes that have fuelled her critics in recent months, the decision to hire little-known former player Ted Oh to shape her swing was seen as the most baffling of all.
Before winning the Mediheal Championship last weekend, Lydia Ko had not won a tournament in 43 events - since the Marathon Classic in July 2016.
Saturday Sport host Brendan Telfer spoke with Kiwi golfer John Lister, who was on the PGA Tour in the 70's and early 80's, on Ko's return to form.
